Can I complete the National Graduate Leadership Programme and then go onto the National Detective Programme afterward?

You would not be able to go onto the National Detective Programme after completing the National Graduate Leadership Programme, as both programmes are geared towards candidates who have no previous policing experience and one does not lead into the other.

However, within your police force, you could potentially take the steps to move into a detective role within your force after completing the two year programme. This would depend on specific force operational procedures, and I would suggest you speak with your local force/the force you may be interested in joining and see if they have any advice and which programme they may suggest you aim for.
